I hope you are NOT storing your date values as varchar in the database, you would be committing a major offence doing that.
I use paramerterised queries and pass a date type into the sp. If I have to pass a string of a date to a proc I use 106 = "dd MMM yyyy" there is NO ambiguity in that format.

hello
Skater.NET offers software licensing/lock - http://rustemsoft.com/SkaterDoc/index.html?order.htm[^]
Price quite reasonable too - but:
(a) Licenser not free so I'm lasing with Skater to see if I can download an "Evaluation Copy"
(b) We do 64 bit, apparent Skater only support 32 bit version!?
(c) Any other suggestion?
Thanks
dev

I don't have a specific third party licensing solution to recommend, but see my answer to your post in the thread about obfuscation: I hope it can give you some ideas.

What I need to do is something like this.
DataCruncher.exe < input.bin > output.bin
It is an application that is called in the command prompt.
The input.bin file is piped in, and the result is outputed to output.bin. Works great.
Now instead of starting the app from a command prompt, I need to call it from a C# app.
ProcessStartInfo info = new ProcessStartInfo(location);
info.Arguments = BuildArgs();
info.RedirectStandardInput = true;
info.RedirectStandardOutput = true;
info.RedirectStandardError = true;
info.UseShellExecute = false;
_process = Process.Start(info);
_toApp = _process.StandardInput.BaseStream;
_fromApp = _process.StandardOutput.BaseStream;
The input is in binary format, and so is the output, so I used the basestream instead of the StreamReader.
My problem is that it is blocking when im reading from the standard output.
while (true)
{
int read = _fromApp.Read(readbuffer, 0, readbuffer.Length);
if (read == 0)
break;
}
It looks like it is blocking the stream until it has all the bytes to fill the readbuffer array.
Is there something I should be aware of when read/writting to a process?

Hi,
the way I understand it, but this could be wrong, I don't have a reference to this, is this:
- the process input and output are designed to be used for text;
- the data is transferred from one process to the other on a line by line basis, and each full line is somehow guaranteed to become available in one go.
So it's my guess you aren't getting any data because there aren't any newline characters in your binary data.
You could experiment with binary data that happens to contain some \r or \n or \r\n sequences, to see whether that splits it in smaller parts.
If so, seems like you should either abandon binary data, or choose another way of communicating (actual files, memory mapped files, ...)

Hi
Thank you for your quick response.
I did some more work on it, and it looks like it was a threading issue.
If I read the out stream in a diferent thread, it does not block. Im not sure why, but it works.
|
|
|
|
|
Yeah, I couldn't tell the threading situation from the code you have shown; if you were performing the reads from the GUI thread (say in a button click handler), then all the GUI changes you ordered in there would not become effective until that handler (i.e. all reads) have finished (unless you added some extra calls such as Invalidate or Refresh).
If you do use a separate thread, that one can't touch any Controls; you would need Control.Invoke for that. This[^] explains it.
And finally, if your data were text, not binary, you could have used the OutputDataReceived event instead of a separate thread...

Yeah, I look at the OutputDataReceived event, and for a moment considered doing reverse text encoding on the string - but that was an absolute last resort 
The threading is handled internally, and has no contact to the GUI.
You can se a sample of it at:

Regards, I am trying to run cmd.exe from a button click event.
this is where I am starting off.
private void button1_Click(object sender, EventArgs e)
{
System.Diagnostics.Process.Start(@"CMD.exe","attrib C:\\save.txt +s +h");
}
when I click on button1 another instance of the program starts.
also the command window never opens.
am I lame?

Try This,
private void button1_Click(object sender, EventArgs e)
{
System.Diagnostics.Process.Start(@"CMD.exe","/C attrib C:\\save.txt +s +h");
}
The only change I have made, is I have added "/C" with the Second Parameter.

How about System.IO.File.SetAttributes instead?

nope...its for file attributes like, readonly, hidden...

Basicly what I am tring to do is change a files properties to super hidden.
(or system hidden) like the protected operating files. read about a way to do this manually
with the cmd.exe(comand line). one could probably build a batch file to do this. But the clean
way would be to do it with in the C# application that creates the file in the first place.
But Im not sure how to go about doing it. the "File.Atributes" only has the general type properties
.It has "hidden" and also "System". But what I need to do is tuck away a file that my program can access And be sure that it wont get deleted or changed.
Any Help would be greatly Appriceated.
Regards;
Rick

I have a Program that displays a List in a textBox such as
Items
Items
Items
is there way that I can make the list in the textBox Click able so that it leads you to a Page depending on which item you click with out showing such as.
http://Site/items
http://Site/items
^_^ thanks for any help.

Does it have to be a TextBox?
This would be fairly trivial if you were using a listbox.

ListBox would be Fine, still don't know how myself so help?
|
|
|
|
|
Create a handler for the Click event, then check the SelectedItems.Item property to determine which item was clicked.
|
|
|
|
|
ok I have all the Code but exactly how to create a Click Handler
private void listBox1_Click(object sender, ??? e)
{
String item = listBox1.SelectedItem.ToString();
System.Diagnostics.Process.Start("http:site" + item);
}
what exactly should I have there?
|
|
|
|
|
The easiest way to create the click handler is the following:
1. Highlight the listbox control
2. In the properties window, choose the "events" view ( the little lightning bolt )
3. Find the click event in the list of events
4. Double-click the click event in the list, and it will create a method stub for you to put your code into

yeah thanks I found that after manually figuring out how to :P
^_^ thanks for all the help.

now I have to ask once you set DataSource is there anyway to full release it?
Additional information: Items collection cannot be modified when the DataSource property is set.
Because the program has a reset feature and this is the error I get when trying to clear the data from the both the listBox and the original list<string>
|
|
|
|
|
Hmm. You're trying to delete an item from the listbox and not from the database?
|
|
|
|
|
never mind I used an unbound list ^_^ thanks for your time though.

My problem seems to be simple, therefore I could not find an answer yet.
I have a windows forms application and the reports are being deployed and uploaded to a binary field in the database. The main idea is to run a query and retrieve this data, storing the report on a byte array. I don't want to compile reports inside the project nor reading them from the hard disk.
Is it possible to set the reportsource for the crystalreport viewer using this byte array or I REALLY have to define a file path on the hard disk? Actually, reading on a buffer, write the file on the disk and read it doesn't seem to be that clever... It'd be nice if we could just read the byte stream of the report template and directly set it as the report source.
Thanks in advance!
